Purpose – The purpose of this paper is to explore the similarities and differences of legal responses to older adults who may be at risk of harm or abuse in the UK, Ireland, Australia and the USA. Design/methodology/approach – The authors draw upon a review of elder abuse and adult protection undertaken on behalf of the commissioner for older people in Northern Ireland. This paper focusses on the desk top mapping of the different legal approaches and draws upon wider literature to frame the discussion of the relative strengths and weaknesses of the different legal responses. Findings – Arguments exist both for and against each legal approach. Differences in defining the scope and powers of adult protection legislation in the UK and internationally are highlighted. Research limitations/implications – This review was undertaken in late 2013; while the authors have updated the mapping to take account of subsequent changes, some statutory guidance is not yet available. While the expertise of a group of experienced professionals in the field of adult safeguarding was utilized, it was not feasible to employ a formal survey or consensus model. Practical implications – Some countries have already introduced APL and others are considering doing so. The potential advantages and challenges of introducing APL are highlighted. Social implications – The introduction of legislation may give professionals increased powers to prevent and reduce abuse of adults, but this would also change the dynamic of relationships within families and between families and professionals. Originality/value – This paper provides an accessible discussion of APL across the UK and internationally which to date has been lacking from the literature. [ABSTRACT FROM AUTHOR]

There is an urgent need for a more effective intervention to slow or prevent progression of age-related macular degeneration (AMD) from its early stages to vision-threatening late complications. Subthreshold nanosecond laser (SNL) treatment has shown promise in preclinical studies and a pilot study in intermediate AMD (iAMD) as a potential treatment. We aimed to evaluate the safety of SNL treatment in iAMD and its efficacy for slowing progression to late AMD. The Laser Intervention in Early Stages of Age-Related Macular Degeneration (LEAD) study is a 36-month, multicenter, randomized, sham-controlled trial. Two hundred ninety-two participants with bilateral large drusen and without OCT signs of atrophy. Participants were assigned randomly to receive Retinal Rejuvenation Therapy (2RT®; Ellex Pty Ltd, Adelaide, Australia) SNL or sham treatment to the study eye at 6-monthly intervals. The primary efficacy outcome was the time to development of late AMD defined by multimodal imaging (MMI). Safety was assessed by adverse events. Overall, progression to late AMD was not slowed significantly with SNL treatment compared with sham treatment (adjusted hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.33–1.14; P = 0.122). However, a post hoc analysis showed evidence of effect modification based on the coexistence of reticular pseudodrusen (RPD; adjusted interaction P = 0.002), where progression was slowed for the 222 participants (76.0%) without coexistent RPD at baseline (adjusted HR, 0.23; 95% CI, 0.09–0.59; P = 0.002), whereas an increased progression rate (adjusted HR, 2.56; 95% CI, 0.80–8.18; P = 0.112) was observed for the 70 participants (24.0%) with RPD with SNL treatment. Differences between the groups in serious adverse events were not significant. In participants with iAMD without MMI-detected signs of late AMD, no significant difference in the overall progression rate to late AMD between those receiving SNL and sham treatment were observed. However, SNL treatment may have a role in slowing progression for those without coexistent RPD and may be inappropriate in those with RPD, warranting caution when considering treatment in clinical phenotypes with RPD. Our findings provide compelling evidence for further trials of the 2RT® laser, but they should not be extrapolated to other short-pulse lasers. [ABSTRACT FROM AUTHOR]
